Best practices
There are a few best practices to consider when dealing with network security:
- Start with UFW: It’s more straightforward and sufficient for everyday firewall needs
- Understand the default policies: UFW denies incoming and allows outgoing connections by default
- Document your rules: Keep track of the rules you add for easier troubleshooting
- Use iptables when more control is needed: Explore its capabilities for NAT, port forwarding, and more
From basic principles to practical application, you now understand the tools necessary to build a robust firewall. Securing your network ensures you can sleep soundly knowing your digital fortress is standing strong.
